About ground cherries
Ground cherries produce hundreds of marble-sized, husk-wrapped fruits with tropical pineapple-citrus flavor, prized for preserves, pies, and fresh snacking.
Spacing & yield
Ground cherries wants 24×36 inches and about 2 lb per plant at ~75 days to maturity.
Growing tips
- Let fruit drop naturally to the ground — fallen husks signal peak ripeness.
- Spread mulch beneath plants to keep dropped fruit clean and easy to collect.
- Start indoors 6 weeks before last frost; growth is slow until summer warmth arrives.
- Stake or cage plants — they sprawl widely and fruit rots if stems contact wet soil.
Common mistakes
- Picking fruit from the plant before the husk turns papery tan; underripe fruit is sour.
- Under-spacing: these plants spread wider than their 24-inch spacing suggests vertically.
- Ignoring self-sowing — ground cherries drop many seeds that volunteer aggressively.
Harvest & storage
Collect fruit after husks turn papery and fruits drop, starting about 75 days from transplant.
Leave in husks at room temperature for 2-3 weeks; refrigerated husked fruit keeps 5-7 days.
Companion planting
Good neighbors for ground cherries: basil, parsley, carrots, onions. Avoid planting beside: fennel, kohlrabi, brassicas.
Planting calendar
Start indoors about 6 weeks before last frost, then transplant 2 weeks after frost. Use the seed-starting calculator above with your real county frost date — the April 15 default is only a worked example (zone 6 style).
